"If" is used in the GMAT in Conditionals only. If you see "if" in a sentence and there's no condition, you should find an answer choice that uses "whether."
Example:
Incorrect:Michael did not know if Margaret was going to come.
Correct: Michael did not know whether Margaret was going to come.
Use "whether" when there is a choice between two possibilities dealing with the same subject.
Example: Jane is not sure whether she should change her job (or not).
"Or not" after "whether" is redundant.
Example:
Incorrect: Jane is not sure whether John is making dinner tonight or not.
Incorrect: Jane is not sure whether or not John is making dinner tonight.
Correct: Jane is not sure whether John is making dinnertonight.
I agree with most of your explanation, but "or not" is not redundant in all cases. When the 2 clauses stand apart, the alternative must be made explicit by introducing "or not" with"whether".
